The embodiments described herein pertain generally to an amalgam electrode, and a producing method of the amalgam electrode, and an electrochemical reduction method of carbon dioxide using the amalgam electrode.
First claim
Opening claim text (preview).
1 . An amalgam electrode comprising a member selected from the group consisting of Hg, Ag, Sn, Cu, Zn and combinations thereof. 2 . The amalgam electrode of claim 1 , wherein the amalgam electrode includes Hg of from 35 wt % to 55 wt %, Ag of from 14 wt % to 34 wt %, Sn of from 7 wt % to 17 wt %, and Cu of from 4 wt % to 24 wt %. 3 . The amalgam electrode of claim 1 , wherein the amalgam electrode is a rod or planar shape. 4 . The amalgam electrode of claim 1 , wherein the amalgam electrode further comprises a copper or tin electrode on one side thereof. 5 . A producing method of an amalgam electrode, comprising: forming an electrode by using amalgam including a member selected from the group consisting of Hg, Ag, Sn, Cu, Zn and combinations thereof. 6 . The producing method of an amalgam electrode of claim 5 , further comprising: forming a copper or tin electrode on one side of the amalgam electrode. 7 . An electrochemical reduction method of carbon dioxide, by using the amalgam electrode of claim 1 . 8 . The electrochemical reduction method of carbon dioxide of claim 7 , supplying a solution containing carbon dioxide into a reduction electrode unit in an electrochemical reactor; and applying current to a working electrode including the amalgam electrode and a counter electrode to reduce carbon dioxide. 9 . The electrochemical reduction method of carbon dioxide of claim 8 , wherein the solution includes a member selected from the group consisting of KHCO 3 , NaHCO 3 , K 2 SO 4 , NaCl, KCl and combinations thereof. 10 . The electrochemical reduction method of claim 8 , wherein the current ranges from 2 mA/cm 2 to 50 mA/cm 2 .
